| // register at the point of an up-call or after handling a suspend check. It reduces the number of |
| // loads of the TLS suspend check value by the given amount (turning it into a decrement and compare |
| // of a register). This increases the time for a thread to respond to requests from GC and the |
| // debugger, damaging GC performance and creating other unwanted artifacts. For example, this count |
| // has the effect of making loops and Java code look cold in profilers, where the count is reset |
| // impacts where samples will occur. Reducing the count as much as possible improves profiler |
